INDEX.

To all WIN/lit it may concern..-

Be it known that I, JAMEB H. RAND, a citizen of the United States of America, and resident of North Tonawanda, in the county of iagara and vented new and. useful Improvements in In dexes, of which the following is a specification.

This invention relates to an overlapping card, visible index, and consists in the novel and improved means for holding the cards or similar index elements in overlapped spaced relation, and in the other novel features, all as hereinafter described and particularly pointed out in the claims.

In the acmnipanying drawings which illustrate certain embodiments of the invention,-

Figure 1 is a front view. of a. group of upstanding cards or index elements embodying the invention;

Fig. 2 is aface view which one of said index Fig. 3 is a rear view merits;

Fig. 4 is a side or edge view of the group in Fig. 1;

Fig. 5 is a front view of a group of de pending cards or index elements embodying the invention;

F ig. G is a face view of the blank from which one of said depending index elements is formed;

Fig. T is a rear View of one of said depending elements; and

Fig. 8 is a side or edge view of the group shown in Fig. 5. i

Referring first to the form of the invention shown in Figs. 1 to 4: Each card or similar index element is made of cardboard, paper or other suitable sheet material, and comprises a body 1, having one margin folded over on itself, as on the line or fold 2, said folded margin being fastened to the body 1 part way from the fold by any suitable means. The preferred fastening means of the blank from of one of said elcas herei shown consists of a row of metallic fastene or staples 3, arranged on a line parallel to the therefrom; but as paste or glue, or stitching, are within the contemplation of the invention.

The end of the folded margin 5, beyond the fastening means, is left free, and is preferably creased on a line 4 adjacent to the part fastened to the card body, and bent Specification of Letters Patent. Application filed August 20, 1318. Serial No.

away from the card body on said pocket, which engages the edge of the next adjacent card or element in the series, thus supslightl porting the cards in upstanding, overlapped,

hosted and spaced re ation, as shown, with their. free margins exposed to display indexcharacters. v ,7

Each card has a. pair of inte rall formed projections 6, extending laterally rom, and adjacent to, the folded edge of the card, to engage the usual channels of an index frame.

he frame is indicated in dotted lines at F, which form the channels being indicated at f f. Said projections G'are of greaterbreadti along the end of the card than the spacing of the cards, so that the projections 6 of successive cards will overlap one another and thus lend supportone to another when the cards are assembled in the frame with the proections 6 engaged by the frame flanges dhis permits the use of lighter materia for the cards than would be possiblewithout such mutual support, and at the same time insures grepter rigidity of the assembled group of cards.

In order to reduce the thickness of the overlapping parts which extend under the frame flanges f, portions of one ply of the folded parts, or so much thereof as overlap the projections of the next card, are-cut away as shown at 7. In the form of the invention now being described the parts out away are at the lateral extremities of the folded over margin. Each card also has a pair of lateral projections. 8 at its free margin to rest on the outer faces of the flang es 7.

Referring now to the form shown in igs. 5 to 8, the card body It has its upper margin folded over on line 2, and fastened as before bya pluralityof fasteners 3. The free end 5' of the folded margin is creased on line 4' and bent on said creased line away from the card body to engage the top edge of the next adjacent card 1n the series. The lateral projections 6 extend under the frame flanges f to support the group of cards when assembled in depending, overlapped, spaced relation; and as in the former case, the projections of successive cards overlap and lend support one to another. In this case, however, the ply of the folded parts which is cut away, thus reducing the thickness of the overlapped portion of the projections, is the body of the card at 7', instead of the end. f the folded margin as in the other form. This makes it possible to swing the cards, forinspection or other purposes, from a point nearer the line of fasteners. The swinging of the cards may be facilitated in the case of the depending cards, where gravity may be relied u )0 to hold the cards fiat in the frame instem of the inherent stiffness of the cards as in the case of u standing cards, by providing each card witi a crease 9, or similar hinge, on which the card body may be swung.

The term card as used throughout the specification and claims denotes any index element of sheet material, whether ofcardboard. commonly so-calld, or other suitable material.
